Citrus oxanthera

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Citrus oxanthera faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its native range in Southeast Asia. The species is particularly vulnerable to genetic erosion through hybridization with commercial citrus cultivars, which threatens the integrity of wild populations. Climate change poses an additional threat by altering precipitation patterns and increasing temperature extremes that affect flowering and fruiting cycles.

Threat summary

Habitat

Citrus oxanthera naturally occurs in tropical and subtropical forest margins, secondary growth areas, and limestone karst formations across Southeast Asia. The species typically grows in well-drained soils at elevations ranging from sea level to approximately 800 meters, often in areas with high humidity and seasonal rainfall patterns.

Frequently asked questions

Why is Citrus oxanthera classified as Endangered?
Citrus oxanthera is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Citrus oxanthera faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its native range in Southeast Asia. The species is particularly vulnerable to genetic erosion through hybridization with commercial citrus cultivars, which threatens the integrity of wild populations. Climate change poses an additional threat by altering precipitation patterns and increasing temperature extremes that affect flowering and fruiting cycles.
Where does Citrus oxanthera live?
Citrus oxanthera occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Citrus oxanthera?
The main threats to Citrus oxanthera are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
